[PATCH v2 1/5] target/riscv: Add svukte extension capability variable

["Fea.Wang" <fea.wang@sifive.com>]

Refer to the draft of svukte extension from:
https://github.com/riscv/riscv-isa-manual/pull/1564

Svukte provides a means to make user-mode accesses to supervisor memory
raise page faults in constant time, mitigating attacks that attempt to
discover the supervisor software's address-space layout.
